System Description
All detectors in the 520 Series are equipped with two optical sensors and a pollution sensor.
The FAP‑OC
520 Multisensor Detector contains a gas sensor as an additional detection
channel.
The response sensitivity of the detector can be programmed with the programming software
via the LSN network. All sensor signals are analyzed continually by the internal signal
evaluation processor and are linked with each other.
By linking the optical sensors and the gas sensor, the OC detector can also be used in places
where the work carried out gives rise to small amounts of smoke, steam or dust. The alarm
will only be triggered automatically if the signal combination corresponds with the
characteristic diagram of the installation location that was selected during configuring.
